ACPI and lockups

[Steve Eclipse]

I've been having occasional lockups that the system log reports as ACPI
related. I understand that this is a BIOS issue. The MB manufacturer has
discontinued support, and will not be issuing any further updates. I know
that I can disable it in the BIOS.

How can I change XP Pro to not use ACPI? (I changed it in the bios and XP
would not boot)

Under device manager it shows the PC as a ACPI computer. How can it be
changed?

Hi Steve -

In order to change XP from the ACPI HAL (Hardware Abstraction Layer), you'll
need to do a reinstall of Windows. This can generally be done using a
Repair Installation procedure.

Boot with your Windows XP CD and choose the option to install Windows.
Allow the installer to detect your current installation of Windows XP and
select it. Take the option to do a repair installation instead of the
option to delete the partition and install clean.

Then, when you're prompted to press F6 to install 3rd party drivers, etc.,
press F5. Scroll the selection to the Standard PC Hal and select it as the
option you wish to install. Windows XP will then be reinstalled in place,
retaining all of your installed programs, drivers and settings. You will
need to reactivate your copy of Windows and you'll also need to reapply all
of the updates from Windows Update (including Service Pack 1).

Before embarking on a Repair Install, it would be prudent to take a backup
of all your personal files and settings (use the Files and Settings transfer
wizard to make backing up your settings easier), just in case you should end
up having to perform a clean install.

Good luck!

Jef,
Outstanding. Thanks a lot for the detailed instructions.

One question though. Since I cannot boot when ACPI is disabled in the BIOS,
so I guess I'll need to do your procedure then on the next reboot disable it
in the BIOS. Or will XP not find it and reinstall the drivers?

Hi Steve -

No need to worry about that detail. Leave ACPI enabled in the BIOS and, if
you can, boot Windows to perform your backups.

Then shut down and restart. Upon restarting, immediately go into your BIOS
and disable ACPI and change your first boot device to CD-ROM. Before you
save your changes, put your XP CD into your CD-ROM drive and exit your BIOS,
saving your changes. When prompted to press a key to boot from the CD-ROM,
do so.

The XP CD will boot regardless of the HAL installed in Windows and you can
then select the option to install, detect your installation and repair it,
selecting the option at the F6 prompt (press F5 instead) for the Standard PC
Hal.

Hopefully I've been clear and good luck!
